This study seeks to evaluate the performance and economic feasibility of the forward osmosis (FO)–reverse osmosis (RO) hybrid process; to propose a guideline by which this hybrid process might be more price-competitive in the field. A solution-diff

Biofouling of reverse osmosis (RO) membranes increases the operation cost of the seawater desalination process, by reducing salt rejection and increasing permeation pressure. However, biocides commonly used to inhibit biofouling not only increase bac

Biofouling is a major problem in operating reverse osmosis (RO) processes. Although biocides such as chlorine are commonly used to reduce biofouling, their strong oxidative activity and toxicity negatively affect the operation of RO processes. 6-ging

Membrane fouling occurs when the operating flux exceeds a certain point (i.e., critical flux). Critical flux has therefore been widely adopted to determine the initial operating flux in membrane bioreactor (MBR) processes. The flux steeping method cu

Membrane bioreactors (MBRs) are considered a promising tool for resource recovery in wastewater treatment. Nevertheless, membrane fouling is an inevitable phenomenon that deteriorates the MBR performance. Although many studies have attempted to eluci
